Online tool for making graphs (vertices and edges)?
Dec 11, 2010 · Anyone know of an online tool available for making graphs (as in graph theory - consisting of edges and vertices)? I have about 36 vertices and even more edges that I wish to draw. …
Proving that the number of vertices of odd degree in any graph G is ...
I'm having a bit of a trouble with the below question Given G G is an undirected graph, the degree of a vertex v v, denoted by deg(v) d e g (v), in graph G G is the number of neighbors of v v. Prove that the …
Number of distinct right triangles formed by connecting vertices of a ...
Mar 9, 2021 · A different way to begin is to think about picking an edge (i.e. picking two vertices of the triangle) to start with. Then how many options are there for the third vertex? Multiply that by the …
What is the name of this 3D shape with 12 outer vertices?
Dec 8, 2017 · The object is the first stellation of the rhombic dodecahedron. This is sometimes known as Escher's solid, for its use in a study for his Stars, though the final picture uses a compound of three …
Prove the existence of a graph of 15 vertices with some vertices degree ...
4 this is the exercise: If possible draw a graph with 15 vertices having 3 vertices with degree 4; 4 vertices with degree 3; 6 vertices with degree 2; 0 vertices with degree greater than the ones of the …
Relationship between vertices and edges in platonic solids
Apr 4, 2025 · The Question: Given a list of the vertices in a platonic solid, is there a way to calculate which vertices are connected by an edge? I know that one could find edges using edge length or …
computer science - Number of edges in a graph with n vertices and k ...
This graph has more edges, contradicting the maximality of the graph. Hence the maximum is achieved when only one of the components has more than one vertex. How many vertices does this graph …
Proof verification: Prove that a tree with n vertices has n-1 edges
Mar 20, 2015 · The proof is incorrect/incomlete. What you are fundamentally saying is that if you have a tree with n vertex and n-1 edges, you can obtain a tree with n+1 vertices and n edges. You can add …
How many nonisomorphic directed simple graphs are there with $n ...
A directed simple graph is a structure consisting of the set of vertices and a binary relation that is irreflexive. For the case of the disconnected graph, the relation is empty, and there is one such …
How to sort vertices of a polygon in counter clockwise order?
16 How to sort vertices of a polygon in counter clockwise order? I want to create a function (algorithm) which compares two vectors v v → and u u → which are vertices in a polygon. It should choose the …
